telescope need electricity, then you need a something more than
batteries. Maybe some kind of large battery that has 5 different
outputs and two flashlights? Sounds good!
tank is a must have accessory for any power-hunger set up. It has
two cigarette-lighter 12v outputs, a 3v output, 6v output, and 9v
output, a low power flashlight with a removable red cap, and an
800000 candle lamp. The mutliple outputs allow you to power your
scope, your dew heaters, and a few other small accersories you might
be using from a single power source. When i first got it, i did not
think the 800000 cangle lamp would be very useful, after all we are
trying to keep light away as much as possible. However, for cleaning
up afterward it is absolutely amazing. With such a powerful light
you can be sure you didn't forget anything on the ground.
experience with the power tank has been limited to powering an EQ-6
with no dew heaters. Power just a single mount the battery has
lasted through multiple observing sessions without needing a
recharge. It has been mentioned that the power supply may be limited
with you start including multiple dew-heater systems drawing power as
well but i have not been able to test this.
product is as simple and straightforward as the review. I needed a
big recharable battery, i got a big rechargable battery with a few
flashlights strapped on. Seems like a good deal to me. And at a
price around $50 it really beats buying batteries.
